Fort Boykin is a historic site in Isle of Wight County, Virginia, located along the James River. The history of the site is believed to date back to 1623 when colonists were ordered to build a fort to protect them from attacking Native Americans or Spanish marauders. The original fort, called The Castle or The Fort at Warroskoyack, would have had a triangular shape and been surrounded by a ditch. The earthworks would have been topped by palisade walls. As those threats became less of a concern, the fort was eventually abandoned.
